RUFFLING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 66 5,519, dated January8, 1901.

Application filed April 26, 1900. Serial No. 14,408. (ModeL) To all whomit may concern.-

Be it known that I, JOHN M. GREIsT, a citizen of the United States,residing at New I-Iaven, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements inSewing-Machine Rufflers, of which-the following is a specification,reference being had therein to the accompanying drawings.

My invention relates to that class of ruffling attachments for sewingmachines in which the ruftling-blade is operated from the needle-bar ofthe machine through the medium of a bell-crank operating-lever on theattachment; and the invention has for its object to provide anattachment of the class referred to which-may be constructedatcomparatively little cost, which may be readily adjusted to vary thestroke of the rufflingblade, and which, while efficientin operation,will be durable, so as to withstand wear.

In the accompanying drawings, Figures 1 and 2 are opposite side views ofmy improved ruffler, and Fig. 3 is a View of the separatorplate and itsholder detached. Fig. 4 is a rear end view of the attachment, and Fig. 5is a plan view thereof. Fig. 6 is a detail view of the false foot.

A denotes the foot portion of the attachment, adapted to be secured tothe presserbar of a sewing-machine, said foot portion A having a lateralextension Ct, which is turned up to form a standard at, these partsconstituting the frame of the attachment.

B is the operating-lever, pivotally mounted on the standard a by meansof the pivot-pin 03, said lever B being forked for engagement with ascrew or projection on the needle-bar of the machine and having apendulous arm b. The lever B is provided with a small ear I), in whichis fixed, so as to be held from longitudinal movement,a screw c,havingamilled head by which it may be readily turned and having a polygonalshank portion which is pressed against by a light plate-spring c toretain the said screw in any desired position of adjustment byfrictional .contact of said spring with the square or polygonal portionof the said screw. The threaded portion of the screw 0 is tapped in afork 0 which is steadied on the pendulous arm I) of the lever B, so thatby turning the said screw in one blade.

e, one portion of which is arranged to slide between a headed rivet a onthe standard a and the lateral extension at of the foot A, the saidblade-carrier being pivotally attached at e to the lower ends of a link9 supported at its upper end on the pivot-pin a the said link beingembraced by the horizontally-extending arms of the vertically-adjustablefork 0 so that as the lever B is operated the arms of the said fork willcome in contact with the opposite sides of the said link to move theblade-carrier and ruffling-blade to and fro. The link 6 is formedsomewhat tapering, as shown in Fig. 1, being narrower toward the upperportion thereof, which is to he engaged by-the said fork, so as toprovide for variations in the throw of the ruffler-blade at both ends ofthe stroke.

- The foot portion A of the attachment is provided with a sole or falsefoot formed of thin sheet metal, so that its portion bearing upon thework may be readily stamped into proper shape, the said false foot inthe present instance consisting of a folded piece of thin sheet metalattached to the said foot A, as by the screw a and overlapping both theupper and under sides or faces of the said foot A, said folded falsefoot being disposed with its fold or bend toward the ruftling- Thisconstruction and arrangement of the false foot prevents any possibleaccidental contact between the ruffling-blade and the end portion of thefoot in such a manner as to endanger breakage of the blade, as hassometimes occurred with previous constructions in which the false footwas secured to the heel of the presser-foot and projected forwardtherefrom, this difficulty being entirely avoided by the presentconstruction of the folded false foot secured to the upper side of therigid foot portion of the attachment and so disposed that it extendsrearwardly from its folded portion, so as to present no obstruction tothe free passage thereunder of the ruffling-blade.

The separator-platef is attached to a holder f, which is secured to theframe or standard a of the attachment by means of a headed stud or rivetf to be embraced by the notched or open-slotted end portion f of theholder, and a screw f engaged by a notch or open slotf in theupwardly-projecting portion f of the holder. To remove theseparator-plate when shirring is to be done, it is only necessary toloosen the screw f when the separator-holder can be turned down todisengage the notch f from the said screw f and said holder may then bewithdrawn from engagement with the rivet f in removing theseparator-plate and its holder from the attachment.

Having thus described my invention, I claim and desire to secure byLetters Patent 1. In a sewing-machine rnfiler, the combination with theframe thereof provided with a suitable standard, of an operatingbellcrank lever pivoted to said standard and having a pendulous arm, arufliing-blade, a carrier for said blade, a pivoted link the lower endof which is jointed to said carrier, and a Vertically-adjustable forkcarried by the pendulous arm of said lever and havinghorizontally-extending arms arranged to loosely embrace the said link.

2. In a sewing-machine rnffler, the combination with the frame thereofprovided with a suitable standard, of an operating bellcrank leverpivoted to said standard, and having a pendulous arm, a ruflling-blade,a carrier for said blade, a pivoted link the lower end of which isjointed to said carrier, said link being somewhat tapering with itsnarrower part upward, and a vertically-adjustable fork carried by thependulous arm of said lever and having horizontally-extending armsarranged to loosely embrace the said link.

3. The combination in a sewing-machine ruffling attachment provided witha foot portion adapted to be secured to the presser-bar of asewing-machine, of a reciprocating ruffling-blade, means for operatingsaid blade, and a false foot secured to the foot portion of saidattachment and consisting of a folded piece of thin sheet metaloverlapping both the upper and under sides of said foot portion anddisposed so as to have its folded portion or bend toward the saidrufller-blade, whereby the latter can pass freely beneath the saidfalse-foot portion of said attachment without danger of positive contacttherewith.

4. In a sewing-machine ruflling attachment, the combination with theseparator-plate f, of a holder to which said plate is attached and oneportion of which is provided with two open slots or notches, anattachment-frame provided with aheaded rivet or stud f and a headedscrew f for detachably securing the said separator-carrier to the frameof the attachment.

In testimony whereof I aifix my signature in the presence of twowitnesses.
